Name the quantity which remains unchanged during the flight of an oblique projectile.

Name the quantity for which the potential difference of a cell becomes less than its emf due to its internal resistance.

A particle charged with 1.6 xx 10^(-19)C is in motion. It enters the space between two parallel metal plates, parallely along the midway between them. The plates are 10 cm long and the separation between them is 2 cm. A potential difference of 300V exists between the plates. Find out the maximum velocity of the charged particle at the point of entry, for which it would be unable to emerge from the space between the plates. Given, mass of the particle = 12 xx 10^(-24) kg .

"A population has been exhibiting genetic equilibrium". Answer the following with regard to the above statement. (i) Explain the above statement. (ii) Name the underlying principle. (iii) List any two factors which would upset the genetic equilibrium of the population. (iv) Take up any one such factor and explain how the gene pool will change due to that factor

In a school, students thought of planting trees in and around the school to reduce air pollution. It was decided that the number of trees, that each section of each class will plant, will be the same as the class, in which they are studying, e.g., a section of Class I will plant 1 tree, a section of Class II will plant 2 trees and so on till Class XII. There are three sections of each class. How many trees will be planted by the students?

Two boats, each with velocity 8km*h^(-1) , attempt to cross a river of width 800 m. The velocity of river current is 5 km*h^(-1) . One of the boats crosses the river following the shortest path and the other follows the route in which the time taken is minimum. If they start simultaneously, what would be the time difference between their arrivals at the other bank ?
